This can be caused by dropping the key fob or by exposure to water. If the key fob is not functioning after exposure to water, it is possible to fix it by cleaning the chip using isopropyl alcohol or electronic cleaner.

Modern fobs come with rubber seals to keep out water. Submerging them in water even if just a light drizzle or splash could damage the chip's electronic components.

The key fob is equipped with an embedded chip that communicates to the immobilizer system of the vehicle in order to start it. The system is based on the old red keys for older vehicles or the cryptocoding system found in modern vehicles. This chip needs to be replaced if it's defective.

A faulty 12 Volt battery

A damaged battery can cause the remote to stop working. The car's computer will not recognize the remote when this occurs.

Test the battery using the help of a voltmeter to determine its capacity. A fully charged battery will display 12.6 volts. If the reading drops significantly the time is now to replace it.

Set an electrical load for a short period of time on the battery to gauge its capacity. This will take away about 1 percent of the charge on the surface. Then measure the voltage again. The longer a battery is able to hold its voltage more effectively, the greater its capacity. Ideally, it will remain close to 12 volts several minutes.

The radio signal is not working properly. Radio Signal

This is the most frequent reason for the key fob not sending signals to the car. The battery can be replaced to fix this issue. It is crucial to buy an identical battery voltage and dimensions as the original.

If your OBD2 scanner won't turn on, check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If these are OK, it's likely that a fuse has failed. This is among the most frequent causes of a scan tool failing. The most straightforward fix is to replace the fuse that is blowing up.
